Helicopter flight controls - Wikipedia
The collective pitch control, or collective lever, is normally located on the left side of the pilot's seat with an adjustable friction control to prevent inadvertent movement. The collective changes the pitch angle of all the main rotor blades collectively (i.e., all at the same time) and is independent of their position in the rotational cycle.
Pitch Control - HeliStart
When flying a helicopter, the pilot is continuously controlling 2 important parameters: the amount of thrust, which is achieved by changing the pitch of all of the blades simultaneously, also known as collective pitch control; and secondly, the direction in which the rotordisc is tilted.

There are three major controls in a helicopter that the pilot must use during flight. They are the collective pitch control, cyclic pitch control, and antitorque pedals or tail rotor control.

As the helicopter nears the ground, the cyclic pitch control is used to slow the forward speed and to flare the helicopter for landing. With the airspeed bled off, and the helicopter now close to the ground, the final step is to use the collective pitch control to cushion the landing.
Helicopter Aerodynamics of Flight - Aircraft Systems
The cyclic pitch control system is designed so that the rotor disc tilts slightly opposite tail rotor thrust when in a hover. Counteracting translating tendency, in a helicopter with a counterclockwise main rotor system, causes the left skid to hang lower while hovering.

Blade pitch question - Vertical Reference Helicopter Forums
2018年5月13日 · The pitch change horn, the part of the blade that sticks out at front or at rear, is attached to the blade, so it will flap and lead/lag along with it, but the swash plate below it, from which the pitch change link comes, does not.
Helicopter Lesson Guides, Darren Smith, Helicopter Instructor
There are four controls in the helicopter that the pilot must use during flight. They are (1) collective pitch control; (2) throttle control; (3) antitorque pedals (auxiliary or tail rotor control); and (4) cyclic pitch control. Figure 27 - Controls of the helicopter and …
Another distinctive technology of conventional helicopters is cyclic control, which describes varying the blade pitch through each revolution of the rotor. This results in a cyclic variation in lift on each blade, a controlled blade apping response, and ultimately useful control authority in pitch and roll derived from only a single rotor ...
